Description

Technical Field

[0001] The utility model relates to the technical field of power cables, in particular to an anti-falling cable junction box. Background Art

[0002] Power cables are used to transmit and distribute electrical energy. They are commonly used in urban underground power grids, power station lead-out lines, internal power supply for industrial and mining enterprises, and underwater transmission lines across rivers and seas. After the cables are laid, in order to make them a continuous line, each section of the line must be connected as a whole. These connection points are called cable joints, and the cable junction box is used to lock and fix the incoming and outgoing lines, and plays a role in waterproofing, dustproofing and vibration-proofing.

[0003] For example, a cable junction box suitable for communication engineering is disclosed in the utility model with authorization announcement number CN217307176U, which includes an insulating sleeve, and a fixing device is provided on the inner side of the outer wall of the insulating sleeve. The structure of the device is scientific and reasonable, and it is safe and convenient to use. Through the cooperation between the second vertical rod, the insulating sleeve, the anti-slip groove and the semicircular plate, the left end screw of the second vertical rod is rotated and removed, and then the second vertical rod is rotated to the right, and then the cables on both sides are passed through the insulating sleeve and connected, and the connected cables are placed in the front end of the anti-slip groove, and then the second vertical rod is reset, so that the semicircular plate and the anti-slip groove are pressed against the cable to form a friction fixation, thereby solving the problem that the contact surface between the junction box and the cable in the prior art is small and the cable is easy to fall off.

[0004] The device forms a friction fixation on the cable by closing the two semicircular plates, thereby increasing the contact area between the junction box and the cable and preventing the cable from falling off easily during vibration. However, during use and installation, the cross-sectional diameters of the cables may be different, and the diameters of the two semicircular plates are fixed and cannot be adjusted. This results in the two semicircular plates with fixed diameters being unable to firmly hold and fix some cables with smaller diameters, thereby affecting the stability of the cable connector connection. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides an anti-falling cable junction box, which can solve the problem that the cross-sectional diameters of cables may be different during use and installation, and the diameters of the two semicircular plates are fixed and cannot be adjusted. This results in the two semicircular plates with fixed diameters being unable to firmly support and fix some cables with smaller diameters, thereby affecting the technical problem of the stability of the cable joint connection.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: an anti-falling cable junction box, comprising a first shell, two bidirectional threaded screws are symmetrically arranged in the first shell for limited rotation, the outer sides of the two bidirectional threaded screws are symmetrically threaded and connected with two sliders, two connecting blocks are symmetrically arranged in the first shell and located between the two bidirectional threaded screws, an arm is hinged between the rear wall of the connecting block and the two sliders, and a number of arc-shaped plates for limiting and fixing the cables are equidistantly arranged on the opposite surfaces of the two connecting blocks.

[0007] As a preferred technical solution of the utility model, one end of the two bidirectional threaded screws is connected to the inner wall of the first shell for limited rotation, and the other ends of the two bidirectional threaded screws are movably passed through the side wall of the first shell and are connected to an adjustment button for rotationally adjusting the bidirectional threaded screws.

[0008] As a preferred technical solution of the utility model, the surface of the adjusting button is provided with rough textures for increasing the friction between the hand and the adjusting button.

[0009] As a preferred technical solution of the utility model, the bottom wall of the connecting block is connected to the inner bottom wall of the first shell in a limited sliding manner.

[0010] As a preferred technical solution of the utility model, a rubber sheet is provided on the surface of the arc plate to increase the friction between the cable and the arc plate.

[0011] As a preferred technical solution of the utility model, one side of the first shell is movably connected to the second shell by a hinge, two explosion-proof interlayers are symmetrically arranged in the first shell and the second shell, semicircular holes are opened at both ends of the first shell and the second shell, and insulating sleeves are arranged at both ends of the first shell.

[0012] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0013] By coordinating the two-way threaded screw with the two sliders, the movement and adjustment of the two sliders towards each other can be achieved. By coordinating the two sliders for movement and adjustment towards each other with the two arm rods, the connecting block can be pushed. By the two connecting blocks that push each other towards each other, the arc plates arranged on the surface thereof are driven to approach the two sides of the cable respectively, so as to clamp and limit the cables of different diameters, thereby improving the stability of the cable connection and the practicability of the device.

[0022] When limiting the position of the cable, first connect the cables on both sides of the first housing 1, then adjust and rotate the adjusting knob 10, and drive the rotation of the bidirectional threaded screw 5 by adjusting the rotating adjusting knob 10, and drive the two sliders 6 to move closer to each other through the rotating bidirectional threaded screw 5, and then push the connecting block 8 through the cooperation of the two sliders 6 and the two arm rods 7 that move closer to each other, so that the two connecting blocks 8 are limited in the first housing 1 and slide closer to each other, and then the arc plates 9 arranged on the surfaces of the two connecting blocks 8 are moved closer to each other, and then the cables arranged between the two groups of arc plates 9 are clamped and fixed;

[0023] As a further implementation of this embodiment, Figure 1-4 As shown, at the same time, one end of the two bidirectional threaded screws 5 is connected to the inner wall of the first shell 1 for limiting rotation, and then the other ends of the two bidirectional threaded screws 5 are movably passed through the side wall of the first shell 1 and connected with an adjusting button 10, and the bidirectional threaded screw 5 can be rotated and adjusted by the setting of the adjusting button 10, and then rough textures are provided on the surfaces of the two adjusting buttons 10, and the friction between the hand and the adjusting button 10 is increased by the setting of the rough textures. At the same time, a second shell 2 is movably connected to one side of the first shell 1 through a hinge, and the first shell 1 can be closed by the second shell 2, and then two explosion-proof interlayers 4 are symmetrically arranged in the first shell 1 and the second shell 2. The explosion-proof interlayer 4 is made of a special explosion-proof aluminum alloy material.

Semicircular holes 11 are provided at both ends of the first shell 1 and the second shell 2, and finally insulating sleeves 3 are provided at both ends of the first shell 1;
